The history of ink

If historians are to be believed, both the ancient Egyptians and the Chinese have developed ink at approximately the same time around 2500. B.C.Most of the ancient cultures around the world have stronglydetermined and framed inks for the purposes of writing and drawing.Chinese used fine particles of carbon called lampblack for the colorant, and gums or glues were the vehicles. In fact, the requirement for ink arose at the same time that art had emerged from cutting into stone and a more fluid medium than an carve was needed.

The introduction of indelible ink

With the introduction of inks, people started using them but one of the disadvantages of using the inks was they can be easily removed. Keeping in mind the requirement, indelible ink was introduced.Indelible means “un-removable”. A number of countries such asIndia, Mexico, Indonesia, Malaysia and so on have been using indelible ink in the form of electoral stain to avoid electoral fraud. Once the ink is placed in the finger, it becomes almost impossible to remove.
